In this study, an optimization model for road maintenance scheduling is proposed. The proposed determines a schedule given set of links in urban network, that minimizes the total travel time during period under assumptions and particular crew number constraint. It assumed all lanes to be repaired are closed traffic maintenance. Ant Colony Optimization (ACO), suitable algorithm discrete transpor...

Abstract This paper addresses the questions: How to calculate cost of a start/stop cycle? running one hour outside normal operating range, e.g., on part load? The presents model for calculation individual hydropower units comprising both direct costs incurring at each cycle, and indirect because reduced rehabilitation intervals main components. fundamental assumption is that frequent start-ups ...

This paper presents one comprehensive modelling approach for maintenance scheduling problem of thermal power units in competitive market. This problem is formulated as a 0/1 mixedinteger linear programming model. Model incorporates long-term bilateral contracts with defined profiles of power and price, and weekly forecasted market prices for market auction. The effectiveness of the proposed mod...
